uitapgesturerecognizer

问题 I'm new to gesture recognizers so maybe this question sounds silly: I'm assigning tap gesture recognizers to a bunch of UIViews. In the method is it possible to find out which of them was tapped somehow or do I need to find it out using the point that was tapped on screen? for (NSUInteger i=0; i<42; i++) { float xMultiplier=(i)%6; float yMultiplier= (i)/6; float xPos=xMultiplier*imageWidth; float yPos=1+UA_TOP_WHITE+UA_TOP_BAR_HEIGHT+yMultiplier*imageHeight; UIView *greyRect=[[UIView alloc

问题 Ok a lot of variables in the title, sorry I couldn't make it any more simpler. First, I have a custom table cell with descriptions like so now, when a user taps on the cell itself, it would go to View A, however, there is a UITapGestureRecognizer that is connected to the UIImage at the left, which is connected to a segue that goes to View B. All is fine, but I need some data that is inside the table view cell that I can pass to View B so it can do some stuff once the view is shown. override

问题 So I have an app that behaves like a photo gallery and I'm implementing the ability for the user to delete the images. Here is the setup: I have 9 UIImageViews, imageView, imageView2, etc. I also have an "Edit" button, and a tapGesture action method. I dragged a Tap Gesture Recognizer over onto my view in IB, and attached it to each one of the UIImageViews. I also attached the tapGesture action method to each of the UIImageViews. Ideally, I would like the method to only become active when the

问题 I'm adding several UIView objects (e.g. 5) to the screen, one inside the other. This, for example, view5.superview = view4 , view4.superview = view3 , view3.superview=view2 , view2.superview = view1 . For all these UIView I set uitapgesturerecognizer; for view1-4 I just do NSLog(@"tap %@", self) in callback, while for view5 tap I set the following: delete view4 from the hierarchy, then put the same object view4' at the same place of the hierarchy. This object also contains view5' for which

问题 I could successfully add tap gestures to a part of UITextView with the following code: UITextPosition *pos = textView.endOfDocument;// textView ~ UITextView for (int i=0;i<words*2-1;i++){// *2 since UITextGranularityWord considers a whitespace to be a word UITextPosition *pos2 = [textView.tokenizer positionFromPosition:pos toBoundary:UITextGranularityWord inDirection:UITextLayoutDirectionLeft]; UITextRange *range = [textView textRangeFromPosition:pos toPosition:pos2]; CGRect resultFrame =

问题 I added two uiimageview s, one on another subview uiview ( imageview1,imageview2 ). In the first view the top uiimageview is hidden( imageview2 ) and in the second view the bottom imageview is hidden( imageview1 ). Allocating tap gesture: UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)]; UITapGestureRecognizer *singleTap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)]; Set user interaction for

问题 I have view with a UITapGestureRecognizer . So when I tap on the view another view appears above this view. This new view has three buttons. When I now press on one of these buttons I don't get the buttons action, I only get the tap gesture action. So I'm not able to use these buttons anymore. What can I do to get the events through to these buttons? The weird thing is that the buttons still get highlighted. I can't just remove the UITapGestureRecognizer after I received it's tap. Because

问题 I have written my own function to scroll text fields up when the keyboard shows up. In order to dismiss the keyboard by tapping away from the text field, I've created a UITapGestureRecognizer that takes care of resigning first responder on the text field when tapping away. Now I've also created an autocomplete for the textfield that creates a UITableView just below the text field and populates it with items as the user enters text. However, when selecting one of the entries in the auto

问题 I am trying to create an action when a user clicks the pause/play button on the Apple TV Remote. I looked at the documentation, but the code Apple's documentation recommended does not work. Here is my code below. Could someone please tell me what I am doing wrong? Things to consider: I am using an AVPlayerMovieController & I do have another gesture recognizer in my code but for it is a swipe gesture AND this method is getting called, just not the Pause/Play. Can someone please help?
